The
Bank of New York Mellon, as Trustee, was a party participating in the servicing function during the reporting period with respect to the pool assets held by the Trust. The Bank of New York Mellon, BNY Mellon Trust of Delaware, and The Bank of New
York Mellon Trust Company, N.A. (collectively BNY) have completed a report on an assessment of compliance with applicable servicing criteria (the Report on Assessment) during the Trusts fiscal year ending
December 31, 2012, which is attached as Exhibit 33.2 to this Form 10-K.

In Schedule A of the Report on Assessment, BNY
identifies two material instances of noncompliance with the servicing requirements of Item 1122 of Regulation AB. In the annual certification provided to Chase USA by BNY, as the Trustee, BNY states that the instances of noncompliance noted in its
Report on Assessment relate to a securitization of manufactured housing receivables and do not relate to the Trust.

The material instances of noncompliance disclosed by BNY did not occur with respect to any securities or transactions of the Trust, and
the reported instances of noncompliance were isolated to other products issued by other entities serviced on BNYs servicing platform. Thus, the instances of BNYs noncompliance specified in Schedule A of Exhibit 33.2 are not applicable to
the credit card receivable-backed securities issued by the Trust.
